Home Products Photoelectric Sensors Omron E3FA Series E3FA-LP21 Omron E3FA-LP21 Photoelectric Sensor Omron E3FA-LP21 is a PNP background suppression (BGS) photoelectric sensor with a fixed 100 mm sensing distance and an M12 connector. It detects targets within 100 mm and ignores objects behind them, so nearby machine parts or walls do not cause false signals, and the connector lets you replace the sensor while keeping the machine-side cable. For the same sensor with a fixed cable, see the E3FA-LP11 2M. It is part of the Omron E3FA Series . Explore more Omron photoelectric sensors .
